Description

Technical Field

[0001] The present invention relates to the technical field of fiber technology, in particular to a porous fiber structure. Background Art

[0002] In recent years, with the increasing impact of climate change and environmental changes, the demand for functional textiles has continued to grow. The development of technological fibers has also made significant progress, resulting in the emergence of a variety of new functional clothing products, such as thermal clothing, UV-resistant clothing, cooling clothing, and moisture-wicking clothing. These products are primarily designed to address the adverse effects of the external environment on the human body, such as ultraviolet radiation, high temperatures, and cold, and to improve wearer comfort. However, while these products excel in passive protection, they have yet to actively enhance human health.

[0003] Limitations of existing technologies

[0004] Passive protection is the main focus:

[0005] Thermal clothing: The main function is to maintain body temperature through material properties or electric heating to prevent the effects of cold on the body.

[0006] Anti-UV clothing: used to block ultraviolet rays and reduce damage to the skin.

[0007] Cooling clothing: Uses special materials to provide a cooling sensation to help the wearer stay comfortable in hot weather.

[0008] Moisture-wicking clothing: Through the moisture absorption and breathability of the material, sweat is quickly wicked away to keep you dry.

[0009] The main purpose of these functional textiles is to passively protect the human body from external environmental damage, such as ultraviolet rays, heat, cold, etc., or to increase comfort by improving the wearing experience.

[0010] Lack of proactive health promotion features:

[0011] Most functional textiles currently available on the market only provide passive protection and lack mechanisms to actively improve human health. Consumers are increasingly demanding improved health, but current products on the market fail to fully meet this need.

[0012] Although some products claim to have antibacterial and antibacterial functions, this still falls into the category of passive protection and cannot truly achieve a positive effect on human health. Summary of the Invention

[0013] (1) Technical problems solved

[0014] In view of the deficiencies of the prior art, the present invention provides a porous fiber structure.

[0015] (2) Technical solution

[0016] To achieve the above objectives, the present invention provides the following technical solutions: A porous fiber structure of the present invention comprises:

[0017] A fiber body, wherein the fiber body is provided in a plurality of forms; and the fiber body is provided with a plurality of cavities for defining a space between each other;

[0018] A plurality of filling particles, including silicon dioxide and titanium dioxide, are filled in the pores.

[0019] Preferably, the fiber body includes an inner peripheral surface and an outer surface spaced apart from each other, and the inner peripheral surface cooperates with the outer surface so that the cross section of the fiber body cut along a direction perpendicular to the length direction is annular.

[0020] Further preferably, the fiber body includes a plurality of radially extending extension segments that are angularly spaced from each other.

[0021] Again preferably, the fiber body is made of synthetic fiber.

[0022] Preferably, the diameter of the fiber body is D1, and the range of D1 is 1nm≤D1≤80nm, wherein D1 includes decimals and integers.

[0023] Further preferably, the particle size of the filling particles is D2, and the range of D2 is 100 nm≤D2≤800 nm, wherein D2 includes decimals and integers.

[0024] Again preferably, the pore size of the cavity is D10, and the range of D10 is 1 μm≤D10≤5 μm, wherein D10 includes decimals and integers.

[0025] Preferably, based on the total amount of the fiber body being 100 wt%, the filling particles account for x wt%, and the fiber body accounts for y wt%, wherein 0.3≤x≤5, 95≤y≤99.7, and x and y both include decimals and integers.

[0026] (3) Beneficial effects

[0027] Compared with the prior art, the present invention provides a porous fiber structure with the following beneficial effects:

[0028] Efficient storage and release of biological information

[0029] Biological signal carrier: Filler particles (mainly silicon dioxide and titanium dioxide) serve as carriers of biological signals and can effectively store and release biological signals.

[0030] Resonance amplification effect: The existence of the pores enables the filling particles to form a resonance effect within the pores, further amplifying the biological information and enhancing its transmission and effect.

[0031] Diverse fiber section designs

[0032] Annular cross section: The fiber body can be designed into a hollow column with an annular cross section (circular O-shaped). This structure not only provides a larger surface area, but also increases the number of cavities, thereby improving the storage and release efficiency of biological information.

[0033] Y-Shaped and Other Cross-Section Shapes: The fiber body can also be designed in various shapes, including Y-shaped, straight-line wavy, and cross-shaped. Different cross-section designs can provide different performance advantages based on specific application requirements. For example, the Y-shaped fiber body can enhance the tensile strength of the yarn.

[0034] Broad application prospects

[0035] Textile applications: The porous fibers can be further twisted into yarn and woven into fabrics, suitable for making T-shirts, polo shirts, pajamas, home clothes, underwear, yoga wear, pants, socks, protective gear, sportswear, bedding and other textiles.

[0036] Improved health and comfort: Due to its efficient ability to store and release biological information, textiles made of this porous fiber can significantly improve the health and comfort of users, such as improving sleep quality, regulating emotions, and enhancing memory.

[0037] Increased tensile strength

[0038] Hybrid cross-section design: By combining fiber bodies of different shapes (such as circular O-shape and Y-shape), yarns with stronger tensile strength can be produced. This hybrid cross-section design not only improves the mechanical properties of the yarn, but also maintains the function of storing and releasing biological information.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] See also Figure 1-5 The porous fiber structure of the present invention realizes efficient biological information storage and release functions by setting multiple cavities in the fiber body and filling them with specific granular materials.

[0047] Example 1

[0048] like Figure 1 and Figure 2 As shown, a porous fiber structure includes a fiber body 1 and a plurality of filling particles 2. The fiber body 1 defines a plurality of cavities 10 spaced apart from each other, and the filling particles 2 are filled in the cavities 10.

[0049] The structure of the fiber body:

[0050] The fiber body 1 is in the shape of a hollow column, and includes an inner peripheral surface 11 and an outer surface 12 which are spaced apart from each other and are cylindrical.

[0051] The inner peripheral surface 11 cooperates with the outer surface 12 so that the porous fiber has a ring-shaped cross section (specifically, a circular O-shape) when cut along a direction perpendicular to the longitudinal direction.

[0052] In other embodiments, the cross section of the fiber body 1 may also be circular or in other shapes.

[0053] Material of fiber body:

[0054] The fiber body 1 is made of polyester, specifically polyethylene terephthalate (PET).

[0058] According to the test report of Taiwan Inspection Technology Co., Ltd. (No. SFW21800628M01), the titanium content in the yarn is about 0.5020wt% and the silicon content is about 0.00446wt%.

[0059] Size parameters:

[0060] The diameter D1 of the fiber body 1 ranges from 1 nm to 80 nm.

[0061] The particle size D2 of the filling particles 2 ranges from 100 nm to 800 nm.

[0062] The pore size D10 of the cavity 10 ranges from 1 μm to 5 μm.

[0063] Weight ratio:

[0064] Based on the total amount of the porous fibers being 100 wt %, the total amount of the filling particles 2 is 1.02 wt %, and the total amount of the fiber body 1 is 98.98 wt %.

[0065] Other possible ratios are 0.3≤x≤5, 95≤y≤99.7.

[0066] Example 2

[0067] like Figure 3 and Figure 4 FIG. 1 shows a porous fiber structure having a structure substantially similar to that of Example 1, except that the cross-section of the fiber body 1 is Y-shaped. Specifically, the fiber body 1 includes three radially extending extensions 13 spaced approximately 120 degrees apart from each other, resulting in a Y-shaped cross-section of the fiber body 1 when cut perpendicular to its length.

[0068] Application of different cross-sectional shapes:

[0069] The number of the extension sections 13 is not limited to three, and may also include but is not limited to one wavy section (straight-wave section), four (cross-shaped), five (star-shaped), etc.

[0070] Example 3

[0071] like Figure 5 As shown, a porous fiber structure includes several circular O-shaped fiber bodies 1 as in Example 1 and multiple Y-shaped fiber bodies 1 as in Example 2. Due to the use of spinnerets of different shapes, fiber bodies 1 with various cross-sections are spun together, producing yarns with stronger tensile strength.

[0082] in conclusion

[0083] The porous fiber structure of this invention achieves efficient storage and release of biological signals by creating multiple cavities within the fiber body and filling them with a specific granular material. Both basic and functional signals can be detected at levels 8 to 10 times higher than the acceptable value, demonstrating significant results and promising applications.
